rs909253

Fasihi et al. investigated the association between three lymphotoxin-alpha (LTA) gene polymorphisms (rs909253, rs1800683, and rs2229094) and the risk of large-artery atherosclerosis stroke in an Iranian population. This case-control genetic association study examined whether these LTA variants contribute to stroke susceptibility in the Iranian cohort.

Association study of 446 Russian schizophrenia patients examining the functional ANKK1 rs2734849 polymorphism and antipsychotic-induced hyperprolactinemia (HPRL). The C allele was significantly associated with higher HPRL risk (OR=1.30, p=0.05 in total group; OR=1.49, p=0.04 in females), while the T allele was protective. This variant likely affects DRD2 expression through NFκB signaling, influencing D2 receptor density on pituitary lactotrophs.

Turkish case-control study examining TRAIL and TRAIL-DR4 gene polymorphisms in gastric cancer. Compared TRAIL C1595T (rs1131580) and TRAIL-DR4 C626G (rs20575) genotype frequencies between 50 gastric cancer patients and 163 healthy controls. No significant association found between either polymorphism and gastric cancer risk (p>0.256, p>0.189) or clinical parameters including tumor stage, lymph node involvement, distant metastasis, and perineural invasion. Serum TRAIL levels were also not significantly different between groups (p>0.33).

This case-control study evaluated 12 SNPs in 8 inflammation-related genes across three studies (Los Angeles, Taixing China, and Memorial Sloan-Kettering) involving 2,049 smoking-related cancer cases and 1,666 controls. IL10 rs1800871 was inversely associated with oropharyngeal cancer (aOR: 0.69, 95% CI: 0.50-0.95) and positively associated with lung cancer among never smokers (aOR: 2.5, 95% CI: 1.3-5.1). TNF rs1799964 was inversely associated with smoking-related cancer in pooled never smokers (aOR: 0.36, 95% CI: 0.17-0.77). After Bayesian correction for multiple comparisons, IL10 rs1800871 and TNF rs1799964 emerged as noteworthy susceptibility markers for smoking-related cancers.

A case-control study of 127 multiple myeloma (MM) cases and 545 controls examined 82 common variants in 45 genes mediating immunity. IL4R rs2107356 (−28120T homozygotes, OR=1.91, 95% CI 1.08-3.38) and FCGR2A rs1801274 (−120G homozygotes, OR=1.95, 95% CI 1.06-3.60) were significantly associated with increased MM risk. A haplotype in the LTA*TNF complex (LTA −82C/−90G*TNF −1036C/−487G/−417G, OR=1.63, 95% CI 1.02-2.61) was also associated with increased MM risk compared to controls.

A large population-based case-control study of TNF-LTA genetic variation in 5,546 breast cancer cases and 5,219 controls (USA and Poland cohorts) found that the variant A allele of rs361525 in the TNF promoter region was associated with modestly increased breast cancer risk (per allele OR=1.18, 95% CI 1.04-1.35, p=0.008). Eight TNF and LTA SNPs were genotyped; haplotype analyses showed the GAG haplotype carrying rs361525 A was associated with elevated risk, while the well-studied TNF-308 variant (rs1800629) showed no association.
